REVOLVING-CYLINDER ENGINE.

SPECIFICATION forming part of Letters Patent No. 301,379, dated .my 1,1884.

, Application led June 16, 1883. (Noiinodell t To @ZZ whom it may concern,.-

Be it known that lI, SIDNEY MALTBY, a citizen'of the United States, residing at lashington, in the District of Columbia., have invented certain new and useful Improvements in Revolving-Cylinder Steam-Engines, of-Which the following' is a specification, reference being had therein to the accompanying drawings.

This invention relates to a steam-engine in which a reciprocating piston plays in a cylinder which revolves on a transverse axis eccen- ,trio to the axis of a fly-Wheel to a Wrist-pin' of which the piston-rod is connected, the main object of the invention being to construct an engine having greatpower and high speed of motion,'\vhile at the same time being of simple, compact, and comparatively inexpensive construction.

My improved engine is adapted to the same 20 uses as other steam-engines, but is especiallj,r intended for driving fans and similar rotary machines, which may have a shaft coupled with or forming an extension or prolongation ofthe ily-wheel shaft of the engine. The invention -consists in certain-novel coinbinations, constructions, and arrangements of parts, which will be fully understood from the following particular description, in connection with the accompanying drawings, in 3o which- Figure l is a side view of my improved engine applied to a fan, the fly-wheel and the fan being shown in vert-ical diametric section. Fig. 2 is a `viewoi' the ily-wheel detached. Fig. 3 is a view of the inner side of the cylinder and one wall oi the casing in which the cylinder-trunnion has its bearing. Fig. 4 is a section of the cylinder and valve and the casing which ineloses the valve in a`- plane into dieated by the line se as of Fig. 5. Fig. '5 is a face view of the valve. Fig. 6 is a side view of the cylinder detached, showing also a face View of the trunnion.

The letter Aindicates a steam-cylinder provided on one side with a trunnion, B, in which are formed steam-passages a a', which connect with passages o t, leading to opposite end of the cylinder in the usual manner. This trunnien has its hearing in one end of a casing, O,

which incloses the valve, (to be hereinafter 5o described) and is secured to a plate, p, which forms one Wall of a casing which incloses the cylinder and iiy-Wheel. From the center of thetrunnion B projects a spindle, B', which has a bearingin an adjustable block, D, which closes, and is firmlyT secured in the outer end of the easing C.

The letterl E indicates the stationary valve, having a central opening, @,Which lits over the spindle B', so as to bring one face of said valve 6o against the end of the trunnion B, While against its outer face is placed the face of a bearing-piece, f, through which the spindle B passes, and which is secured to the block D. Outside of this block l) the spindle B is slotted, and provided with a key, d, by in'eans Of which the block D may be adjusted to cause the bearing-piecej" to have greater or less frictional pressure against the valve, as desired. The valve E is provided with flanges or rims e 7o e, between which and the trunnion, and between which and the edge of the bearing-piece f, are arranged packing-rings e2 e?. The valve E is provided on one side of its central opening With two through-ports, g g, and on the other side with two similar ports, g g3, the ports g and g being connectedby a passage, l1., and the ports g2 g connected by a passage, h. The steam-supply pipe l is connected with the passage h, and the exhaust-pipe I is connected- 8o with the passage it. The iloiv ofsteani through the pipe I is controlled by athrottle-valve operated by governor, K. Any suitable governor may be used; but I prefer to use the special forni of governor which is shownin the drawings, but will not be here particularly described, as it will form the subject of a separate application for patent.

The operation of the valve E will be hereinai'ter described in connection with the opera 9o tionV of the complete apparatus.

The letter L indicates the fly-wheel, which, it Will be observed, is fixed upon a shaft, M, which is not concentric orin line with the axis about which the cylinder A revolves, but is in opposite ends of the cylinder, and the rod n has its outer end connected to a Wrist-pin, on.,

projecting from the iiy-Wheel. The shalt M has its bearings in the opposite end walls of a casing, I?, which incloses a fan, Q, the fanarms q q of which project radially from said shaft, so that while, in the present instance, the said shaft M is .the main driving-shaft o-f the engine, it is also the fan-shaft. Upon the inner side ofthe cylinder isa stud, Sand upon the inner end of the shaft M is a stud, S', and these two studs are connected by a link, S2, which, as the cylinder and shaft revolve, serves as an inner support for the cylinder, and to a great extent relieves the bearings of the cylinder-trunnion, and of the shaft M of lateral strain, so that the axes of the fly-wheel and cylinder Will not be Aforced out of parallelism.

Uponthe outer end of the shaft M, which projects through the casing I?, is fixed a pulley, R, which may serve to carry a power-transmitting belt when required. Upon the outer face of this pulley is a wrist-pin, o, to which is connected one end`of a link, o", the other end of which is connected tothe plunger of a feed-pump, T, which may be connected for supplying the boiler with feed-water.

rllhe special construction of the pump will not here be particularly described, as it will form the subject of a separate application for patent, as will also an automatic valve, indicated by the letter X, and intended to regulate the supply of feed-Water to the boiler.

The constructions of the fan and itsregulating devices and of the feed-pump are not here particularly described, as a description thereof is not essential to an understanding of my present improvement in steam-engines.

The operation of the invention is as follows:

`When steam is admitted to thevalve'passage the passage h and exhaust-pipe. In the meantime the movement of thev piston-rod drives the wheel, Which, in turning, carries the cylwhich had been receiving steam is carried to an exhaust-port of the valve, and the passage which had been exhausting is at the same time brought to a supply port. This operation continues as long as the steam is supplied.

A steam engine has heretofore been construeted with a cylinder arranged to revolve upon a transverse axis7 and having its pistonrod connected with a wrist-pin of a iiy-Wheel, the shaft of which is in a plane parallel to the axis of the cylinder; and I of course lay no claim to such an engine, broadly,

That I claim isl. The coinbinatioinwith the cylinder having its'pistourod connected to a wrist-pin of an eccentrically-mounted ily-Wheel,and provided withlthe trunnion having steam-passages connected with opposite ends of the'said cylinder, of the valve E, provided with the throughports connected in pairs by passages, as described,and the bearing-piecef, placed against the outer face of said valve,substantially as described.

2. rlhe combination, with the cylinderhaving the suitably-mounted trunnion B,provided with steam-passages connected with its opposite ends, the spindle projecting from said trunnion and provided with a suitable bearing, and the piston having its rod connected to a revolving element, ofthe stationary valveE, provided with the ports connected'in pairs, said pairs being connected, respectively, to supply and exhaust pipes, and the beariiigf, the whole constructed and arranged to operate substantially as described.

3. rlhe combination, With the steam-eylin der arranged to revolve upon atransverse axis, and the shaft of the ily-Wheel which is in a plane .parallel to that of said axis, of the link having one end pivoted upon the iy-wheel shaft and the other pivoted upon a stud projecting axially from the cylinder, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

SIDNEY MALTBY.
